  • Linux file server for an inexperienced admin

    - by Pat
    A charity I volunteer for wants a file server for their mostly Windows machines (about five XP and 7 machines, with some Mac laptops every now and then). For the server, I have a PC with an Intel Core 2 Duo 3GHz proc, 4GB of DDR2 400MHz RAM, and a 500 GB HDD. (I should point out that they do not currently have any server - they are just using Windows to share a folder on one of the PCs.) What is a linux distro that is easy to configure for Windows file serving yet stable and secure enough to protect sensitive data without an expert sysadmin? I'm guessing that a Debian distro would probably fit the security bill, but I don't know of any tailored to novice sysadmins. Also, are there any killer apps for making this easy to administer and set up (as a Windows file server, in particular - this answer is a good example)? Would FreeNAS be sufficient? Once it's all set up, what are the minimum measures I need to take to keep the data secure? I found this somewhat helpful answer, but it's not specific to my question of just getting a secure file server up, running, and maintained.

  • xargs command works on ubuntu, but not mac

    - by Corey Hart
    I have the following line of code that I use to update my personal date variable in my projects to todays current date. This line works in Ubuntu's terminal, but the Mac terminal seems to be far behind. Unfortunately, I copied this snippet from some site, so I'm not sure how it exactly works. Suggestions? grep -ilr --exclude=revar.sh --exclude=README.md "[DATE]" * | grep -v .git | xargs -i@ sed -i "s/\[DATE\]/${today}/g" @

  • Redhat Linux password fail on ssh

    - by Stephopolis
    I am trying to ssh into my linux machine from my mac. If I am physically at the machine I can log in with my password just fine, but if I am sshing it refuses. I am getting: Permission denies (publickey,keyboard-interactive) I thought that it might be caused by some changes that I recently made to system-auth, but I restored everything to what I believe was the original format: #%PAM-1.0 # This file is auto-generated. # User changes will be destroyed the next time authconfig is run. auth required pam_env.so auth sufficient pam_fprintd.so auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 500 quiet auth required pam_deny.so account required pam_unix.so account sufficient pam_localuser.so account sufficient pam_succeed_if.so uid < 500 quiet account required pam_permit.so password requisite pam_cracklib.so try_first_pass retry=3 password sufficient pam_unix.so md5 shadow nullok try_first_pass use_authtok password required pam_deny.so session optional pam_keyinit.so revoke session required pam_limits.so session [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid session required pam_unix.so But I still could not ssh in. I tried removing my password all together and that didn't seem to help either. It still asks and even entering an empty string (nothing) it still fails me out. Any advice?

    I am trying to change the titlebar of a window in Mac OS X. To be specific I am trying to this with firefox. And I want to draw/put a bitmap on the title bar and also min, max, and close buttons.

  • Renaming VLAN Interfaces in Linux

    - by rhololkeolke
    I need to know how to rename VLAN interfaces. I'm currently running Ubuntu 11.04. I'm running a networking application that takes frames on one interface applies things like delays and errors and then forwards the frames out another interface. The default naming convention which names things <interface>.<vlan> e.g. eth0.2 will not work for my purposes because the program which parses the configuration script for the networking application doesn't like the decimal in the interface name. I ran vconfig set_name_type VLAN_PLUS_VID which solves the decimal in the interface name problem, however, I can then no longer assign the same vlan id to multiple interfaces because they have the same name. I know how to change physical interface names using udev rules, but because the vlan's will have the same MAC address and they aren't physical interfaces I can't use those rules to rename the interfaces. Is there a way to rename any interface in linux, including the virtual ones? Is there a way to specify your own naming convention for config set_name_type option without having to recompile the source of vconfig?

  • VirtualBox error VERR_SUPDRV_COMPONENT_NOT_FOUND

    - by ant2009
    I am using Fedora 12, with kernel stv-fedora 2.6.31.12-174.2.22.fc12.i686 I have install VirtualBox OSE v3.1.4-1.fc12. When I start VirtualBox I get the following error: Failed to start the virtual machine WinXP32. Failed to open/create the internal network 'HostInterfaceNetworking-eth0' (VERR_SUPDRV_COMPONENT_NOT_FOUND). One of the kernel modules was not successfully loaded. Make sure that no kernel modules from an older version of VirtualBox exist. Then try to recompile and reload the kernel modules by executing '/etc/init.d/vboxdrv setup' as root (VERR_SUPDRV_COMPONENT_NOT_FOUND). However, if I run /etc/init.d/vboxdrv setup I get this error: -bash: /etc/init.d/vboxdrv: No such file or directory How do I get rid of the error and run VirtualBox?

  • Specify IPSEC port range using ipsec-tools

    - by Sandman4
    Is it possible to require IPSEC on a port range ? I want to require IPSEC for all incoming connections except a few public ports like 80 and 443, but don't want to restrict outgoing connections. My SPD rules would look like: spdadd 0.0.0.0/0 0.0.0.0/0[80] tcp -P in none; spdadd 0.0.0.0/0 0.0.0.0/0[443] tcp -P in none; spdadd 0.0.0.0/0 0.0.0.0/0[0....32767] tcp -P in esp/require/transport; In setkey manpage I see IP ranges, but no mention of port ranges. (The idea is to use IPSEC as a sort of VPN to protect internal communications between multiple servers. Instead of configuring permissions basing on source IPs, or configuring specific ports, I want to demand IPSEC on anything which is not meant to be public - I feel it's less error-prone this way.)

  • dynamic routing between openvpn tunnels

    - by pQd
    i'm thinking about using dynamic routing [ OSPF or RIP ] via OpenVPN tunnels. right now i have few offices connected in full mesh, but this is not scalable solution as we add more locations. i would like to avoid situation when plenty of internal traffic is affected if one of two vpn termination points that i plan to use is down. do you have similar configuration working in production? if so - what routing daemon did you use - quagga? something else? did you encounter any problems? thanks!
